The optimized inner projection (OIP) technique, which is equivalent to the method of intermediate Hamiltonians (MIH), is applied to the PPP and Hubbard models of the benzene molecule. Both these methods are applicable since the electrostatic part of the PPP and Hubbard Hamiltonians is positive defin
We present some discussions on the ground state of the Hubbard model on the bipartite lattice with finite Coulomb interaction. Our theory is based on a graphical method. First we apply it to the ld Hubbard model and secondly we discuss the 2d Hubbard model.
